Why MDF Radius Corners

The Problem This Solves

⌒

L Corner — 4″ Radius

The L Corner profile at 4″ radius is the workhorse of the radius corner lineup. The two-leg geometry integrates with both the front face and the side panel of the cabinet box — a cleaner, more complete corner solution than the Econo Quarter Round for full-height cabinetry and built-ins.

▣

Double Refined MDF

Double Refined MDF machines cleanly, paints to a flawless finish, and holds its shape over time. No grain inconsistency, no void risk — just a consistent, dense substrate that takes primer and paint the way cabinetry demands. A surface indistinguishable from solid wood when properly primed and painted.

★

Only National Manufacturer

White River Hardwoods is the only national manufacturer of MDF radius corners in the USA — made in Fayetteville, AR. Consistent quality, reliable availability, and a supplier that has been delivering to the cabinetry industry nationally for decades.

⊞

Accepts 3/4″ Plywood

Engineered specifically for 3/4″ plywood box construction — the standard substrate for this profile. The plywood box butts cleanly into the radius corner without shimming, scribing, or custom fitting. One piece, right the first time.

Installation

Working With Radius Corners

1

Plan Your Layout

Determine the location and orientation of each radius corner. The piece is 97″ long — cut to your finished height. Mark cut lines accurately before cutting; MDF does not forgive mis-cuts at visible faces.

2

Cut to Height

Cut with a fine-tooth carbide blade — MDF dulls blades quickly. Cut from the finish face to minimize tear-out. Support the full length when cutting to prevent binding and chipping at the cut line.

3

Dry Fit First

The 3/4″ plywood box should seat cleanly into the radius channel. Dry fit before applying any fasteners or adhesive — confirm seating depth and check that the radius face is flush with adjacent cabinet faces.

4

Fasten & Secure

Secure with construction adhesive and finish nails or screws through the cabinet box. Pre-drill to avoid splitting. Set fasteners slightly below the surface — MDF fills cleanly and holds fasteners well when properly pre-drilled.

5

Fill & Prime

Fill all nail holes and seams with lightweight filler. Sand flush when dry. Apply a quality MDF primer before finish coats — MDF is highly absorbent and requires a sealing primer coat for a smooth, paint-ready surface.

6

Finish to Match

Apply your chosen paint in thin, even coats over the primed surface. Two finish coats over primer is standard for a smooth painted cabinet finish. Sand lightly between coats with 220-grit.

Always Prime MDF Before Finishing

MDF is highly absorbent at cut edges and faces. A quality MDF-specific or high-build primer is essential before any finish coat. A properly primed MDF radius corner paints to a finish indistinguishable from solid wood — skipping the primer step results in an uneven surface that requires significant additional work to correct.

Comfortable and Classic Dress Shoes That Look Great All Day
Size: 12, Color: Cognac
These dress shoes have been a great addition to my wardrobe. Right out of the box, they felt comfortable thanks to the cushioned foam insole. I can wear them for long days at work or events without my feet feeling sore, which is something I really appreciate. The faux leather upper looks polished and well-made. The cap-toe design and subtle contrast stitching give the shoes a classic, professional appearance that pairs perfectly with dress pants or a suit. They have a clean, timeless style that never feels outdated. The fit is true to size, and the lace-up closure provides a secure and adjustable fit. I also like the stability of the stacked heel and the non-slip sole, which gives me confidence when walking on different surfaces. Overall, these shoes deliver both comfort and style. They look sharp, feel supportive, and hold up well with regular use. I am very happy with this purchase and would definitely recommend them to anyone looking for reliable, classic dress shoes.
